After asking too many murder-related questions online (for your book), you get an invite to a... serial killer chatroom?! What the...?
SO YOU'RE A SERIAL KILLER. SUPPOSEDLY.
A reporter by day, an aspiring writer by night: you've been asking all the important questions on the dark web.
Like, how do you bury a body? How do you kill someone with a crowbar with the right angle to cause blunt-force trauma? What's the best way to hide from law enforcement?
If you're to write a good crime book, this is how you'll do it.
Suddenly, ERROR! UNKNOWN invites you to a server... with a warning. "don't be so obvious smh You're Gonna Get Caught".
...
It's a serial killer chatroom.
You may be slightly screwed.

WELCOME TO HELL, LOSERS!
Play as a (fully customisable!) character as you…
Desperately pretend to be a serial killer. So they don't kick you out. Or kill you. Oh god, they might kill you.
Get to know some killers. You might as well. No better chance to gather accurate first-hand data for your book.
Huh, they're actually kind of nice?
Oh shit, he's hot. And she's hot.
Maybe you can… date… some murderers?
What even is your life.
Yup, you heard us right! Killer Chat! is a dark satire romance chatsim where you date serial killers. Pretend to be a serial killer, get inspiration for your book, fall in love, and try not to call the cops through a whirlwind six months with your murderous beau of choice. Who knows? You might find your happily ever after... or headline the news as a gruesomely lovesick corpse. It's honestly up to you.

MAKE THE SLAUGHTERHOUSE YOUR SLAUGHTERHOME!
🫀 Get to know your fellow serials through DMs, group calls, voice & video calls (and spam their friend requests).
🔪 Express yourself by changing your bio, profile pic, server roles and statuses!

🫀 Keep yourself guessing with random character events in each playthrough.
🔪 Unique relationship dynamics with all characters in every playthrough. Develop wonderful (or hostile!) relationships with the server members with expanded friendship routes! Be warned - these interactions will now have a significant impact on the plot... and your lifespan.

OUTSIDE THE CHATROOM
As much fun as risking your life lying to a bunch of murderers is, sometimes you need a break. You can now access your PC desktop, where you can:
📝 Write your book (it’s the only reason you’re there, right?)
💌 Write love letters (okay, maybe not the only reason…)
🎮 Play some minigames!
🪞 Change your appearance with our virtual closet.
🏆 Keep track of your achievements.
🔍 Keep track of your knowledge and relationships with the server... for research purposes.
BE WHO YOU WANT TO BE!

Play as a customisable MC!
In addition to your appearance, you can customise your:
🖊️ Name/Username
⚧️ Gender
🏳️🌈 Sexuality
♒ Personality
🕵️ Alibi and Moniker (we’re sure you’ll come up with something convincing…)
🔪 What kind of pseudo serial killer you are!
Your customisation and choices will impact dialogue and relationships, making each playthrough feel more distinct and your MC feel alive (... or dead).

CONTENT WARNINGS:
Killer Chat! Expanded Edition contains references to death, murder, abuse, loss, ableism, and transphobia.
MEET THE SERIALS!


AND THE REST...
(An arsonist, a slasher out of the '90's, a surfer who trips into killing, a lonely hearts poisoner... you'll have to play the game, won't'cha?)
